摘要
提出了一种航天器附着（软着陆）小行星的制导与控制规律.为了保证垂直软着陆,事先规划了满足约束的理想视线与视线角轨迹,通过设计滑模变结构控制器跟踪理想轨迹,实现了在小行星表面垂直软着陆;证明了制导与控制规律的鲁棒性;最后通过数学仿真验证了提出的制导与控制规律的可行性.
A guidance and control strategy for attaching a vehicle to a small solar system body is presented. In order to ensure soft-landing, a prescribed line of sight and angle of sight profile satisfying restriction are planned, a sliding mode controller is designed to track the prescribed line of sight and angle of sight profile for safely soft-landing on surface of small asteroid. The robust feature of the close-loop guidance scheme is stressed. Finally, numerical simulations are conducted to verify that the given guidance and control strategy is feasible.
